Welding Tips and Tricks

LtBadd wrote:looks real good Sam, are you just tacking and welding or doing the cutting of the pipe also?

I cut the tubes on a lathe and then used a miter gage on a belt sander to sand the angle. This was all done before I left on Friday, I just took everything home to weld it.

I love seeing all the great looking weld posted here. Myself, I wanted to learn tig welding to do small fabrication and repair of stainless steel parts for boats. Today I was able to help a friend by welding a mount back onto a porthole frame. Not a lot of welding just 4 tacks from 16 gauge to .025. While it was not the best looking weld it made him smile.

also 2 other small boat projects

This last month or so

Seems perfect well done.Very nice bright welding I wonder what is the flow of argon gas protection isi perfect and how you can achieve this king of shine weld apart the skill that it is obvious that is outstanding...Bravo.. Some how o pro must show
quality of welding that is ahead of the average welder .

Started working last night on a 16 inch 300# steam main under ground. There still digging up pipe trying to find the leak. It has an insulation case and a welded 24inch jacket. If they can't find the leak visually then there going to bring in a smart pig. It's a robot that can ultrasound the pipe from the inside. Either way we will be cutting off the jacket and repairing the pipe, or cutting out some holes big enough to get the robot in. We only have a one week window so it may not all happen this week. I'll post more pics as I can.

This week

i see you do numerous shapes and fixtures.
do you have several customers or do you build for one source?

I work for North River boats so most of the things you see are for them.

@5th Street Fab

Just out of curiosity, are the long runs that you do done with mig? Do you use both processes?

It depends. I try to tig anything that will be seen or anything that's critical. Everything else is migged.

Hey all, recently started welding and TIG welding and have been trying to get some practice in. I don't nearly get around to it as much as I should.
Really see some amazing work being done here on the forum, truly incredible!

Some of the sides are not looking too good and I can only assume way too much heat on the stainless part
Have been struggling a bit with the stainless for some reason, I'm thinking my filler it too thick so I can't move as fast as I want to.
Hopefully I will tackle a more useful project soon, i.e. aluminium water tank for my car.
Also got my TIG finger combo, was pretty expensive to get it to me, but definitely worth it considering the wealth of knowledge that is available.

Welds look good from a consistency perspective, but way too hot. With stainless, heat control is a major challenge. A few fusion tracks to hold the sides together, then weld only one edge. Let cool! Then weld another edge elsewhere. Let cool! And keep rotating to farther edges. Stainless is terrible at dissipating heat, so patience and input control is paramount.

Maybe a smaller wire too for that project. It takes a lot less amps to weld stainless than the equal thickness carbon steel.

Thank you for that advice! I really didn't give this piece a chance to cool in between welds.
I think next time I should make a few of them at the same time, that way I can keep busy but also let them cool in between. I'm also learning that having little jigs or something to help you hold things is really important in making your life easier.

“I have too many clamps” said no welder ever-

My wife asked me to make this bit 3/8" narrower, taking half off each side. The hard part was making a fixture to hold it in the same angle for rewelding, and not have it warp. It's some kind of polished stainless. The bead came out looking pretty nice but I had to make it smooth because the horse bites down on the part where the weld is. So I used a flap disk then successively finer grained sand paper.

A simple poling platform but challenging because of the compound angles and keeping it all symetrical.

Looks very professional!

Looks great Warren, I hate compound angles!

Yeah. They are aggrevating. The stern leans forward and angles out and the mounting points are wider than the top. And the sides are mirror images so you cant just copy direct.
